Abstract
1439132 Hydrophilic polymer products SPECIAL POLYMERS Ltd 12 March 1973 [13 March 1972] 11627/72 Headings C3P and C3G A hydrophilic polymer product is prepared by polymerizing a mixture of (1) a hydrophilic monomer selected from N-vinylpyrrolidones and hydroxyalkyl methacrylates and a hydrophobic monomer selected from alkyl acrylates, alkyl methacrylates and styrene or (2) N-vinyl- 2-pyrrolidone and/or hydroxyethyl methacrylate and a hydrophobic polymer selected from nylons, polyamides of terephthalic acid with one or more alkyl-substituted hexamethylene diamines, poly-(alkyl acrylates), poly-(alkyl methacrylates), polystyrene, polyvinyl chloride and bisphenol A polycarbonate, the polymerization being effected by means of electromagnetic radiation in the ultraviolet ray-gamma ray range in an environment free from any chemical polymerization initiator and from any residue of such initiator. Polymerization is preferably effected in vacuo or in an inert gas atmosphere. Products obtained using mixture (2) may be in the form of a graft polymer. The polymerizable mixture may also include a crosslinking monomer, e.g. divinyl benzene, allyl methacrylate or ethylene glycol dimethacrylate, and additives such as molecular weight regulator solvents, extending or swelling agents (e.g. water or glycerol) dyes and therapeutic substances. Shaped products are obtained by effecting the polymerization in a mould or shaped reaction vessel. Uses include contact lenses, protective corneal fittings, prosthetic devices, surgical implants, dialysis membranes for artificial kidney machines, and carriers for oral administration of drugs.
